NaNO3 Sodium Nitrate White Powder 25 KG / BAG Used as Quenching Agent
Sodium nitrate is colorless transparent or white with yellow rhombic crystals, its taste is bitter and salty, soluble in water and liquid ammonia, slightly soluble in glycerol and ethanol, easy to deliquesce, especially in the presence of a very small amount of sodium chloride impurities, sodium nitrate deliquescence is greatly increased, when dissolved in water, its solution temperature is reduced, the solution is neutral, when heated, sodium nitrate is easy to decompose into sodium nitrite and oxygen.

1. Glass Industry: Sodium nitrate is used as a clarifier and decolorizer in glass manufacturing. It can reduce the viscosity of the glass liquid and make the air bubbles in the glass easier to be discharged, so as to improve the transparency and quality of the glass, reduce the impurities and colors in the glass, and make the glass more pure and colorless.
2. Enamel Industry: Used in the preparation of enamel glaze, it can help reduce the melting point of the glaze, promote the uniform adhesion of the glaze on the metal surface, improve the gloss and corrosion resistance of the enamel, and make the enamel products more beautiful and durable.
3. Metallurgical industry: In the process of metal heat treatment, sodium nitrate can be used as a quenching agent, which can make the metal parts obtain good hardness and toughness and improve the mechanical properties of metal. In addition, it can also be used for metal pickling and descaling to remove the oxidized layer and rust on the metal surface.
4. Chemical raw materials: Sodium nitrate is an important raw material for the preparation of other nitrates, nitrites and nitric acid. For example, by reacting with sulfuric acid, etc., it can prepare nitric acid, which is an important chemical raw material widely used in fertilizer, explosives, dyes and other industries. It can also be used to produce sodium nitrite, which has important uses in food processing, water treatment, and other fields.
